On-time delivery
The receipt of scheduled shipments on the expected date, or defined as being within an allowable early/late tolerance. Some measurements include adherence to a specified delivery time of day due to unloading or space constraints.
Open circuit voltage (OCV)
Open-circuit voltage is the difference of electrical potential between two terminals of a device when there is no external load connected, i.e. the circuit is broken or open.
Operating system
A structured set of system programs that controls the activities of a computer system by managing memory, tasks and communications.
Operation
A production step or activity with a defined start and stop time that may be composed of individual tasks but is not broken down into smaller increments in rate and capacity calculations.
Operation qualification (OQ)
Demonstrates that all facets of the process or equipment are operating correctly.
Operational acceptance testing
Also known as operational readiness testing, this refers to the checking done to a system to ensure that processes and procedures are in place to allow the system to be used and maintained. This may include checks done to back-up facilities, procedures for disaster recovery, training for end users, maintenance procedures, and security procedures. Also see FAT.
Operator interface (OI)
The hardware and software that shows an operator the state of a process (also see HMI).
Optical Character Recognition (OCV)
OCV is the machine recognition of characters by light-sensing methods.
Optimization
A process of orchestrating the efforts of all components toward achievement of the stated aim so everyone gains.
Original Equipment Manufacturer (OEM)
An Original Equipment Manufacturer provides final systems made from assemblies and subassemblies from other manufacturers.
Orienter
A random component orienting approach that is generally used when a component is fed, but is out of orientation, and need to be 100% oriented before further processing.
Oscilloscope
A Hardware debugging tool that allows you to view the voltage on one or more electrical lines. For example, you might use an oscilloscope to determine if a particular interrupt is currently asserted.
OSHA
Abbreviation for the United States Occupational Safety and Health Administration (OSHA), an agency of the United States Department of Labor. Its mission is to prevent work-related injuries, illnesses, and occupational fatality by issuing and enforcing standards for workplace safety and health. The agency is headed by a Deputy Assistant Secretary of Labor.
Output
The electrical signal measured at the output terminals which is produced by an applied input to a transducer.
Overall Equipment Effectiveness (OEE)
Overall equipment effectiveness (OEE) is a hierarchy of metrics developed to evaluate how effectively a manufacturing operation is utilized. It incorporates loading, availability, performance and quality factors.
Overload device
Devices such as collapsible links, pop-out clutches, or auto-opening electrical interrupters used to prevent damage or injury to machines, automated equipment, or operators as a result of a mechanical or electrical overload.
